The plate designation seems to be wrong

UNS 312254

The designation shall be 

SA 240 UNS 31254

Pl correct if I am wrong .

Pl mention what is service process application ?

For TYP31254 , ERNiCRMo10 shall be used if PREN  required is higher and pitting corrosion is prime requirement

UNS 312254 falls under the category of Super Austenitic stainless steel and commonly know as 6Mo alloy or 254SMO.

The Filler wire you are using ER 2594 is not correct and it  is for Super Duplex stainless steel with alloying ellements on lower side.

The correct Filler metal to weld UNS 31254 is  ERNicrMo3 for which the F-No is 43 and hence you cannot use the existing WPS.
